This Paper is aimed to present the design and implementation of a one kilowatt capacity single phase grid tie photovoltaic inverter. The proposed design and simulation process of this system is in PSIM simulation environment. The reason for choosing the software PSIM is that it provides the solar module facilities. For single phase grid tie inverter design some special types of consideration, like reference voltage creation to synchronise the inverter's output with grid, PWM (Pulse Width Modulation) signal creation by comparing the reference and triangular wave, is designed and simulated precisely. According to the PWM pulses, the solar module provided DC voltage is switched by using single phase bridge inverter circuit. After filtering and matching the inverter's AC output wave's amplitude and frequency with grid, this AC power is given to the grid by using isolation transformer. All of these fundamental criteria of an inverter are met in this inverter design. After analysing the simulated output a hardware prototype is also implemented. In hardware prototype, according to the reference signal, PIC18F4431 microcontroller is used for generating the PWM pulses. These PWM pulses act as the switching controlling pulses for IGBT (Insulated Gate Bipolar Transistor).

Photo Voltaic is emerging as a major power resource with low-carbon economy promises a brighter, cleaner future. A grid-tie inverter converts direct current electricity into alternating current electricity and feeds it into an existing electrical grid. The grid-tie inverters inject power into the grid as long as the renewable sources are active. However during night hours, inverters will remain idle. This reduces the utilization of these inverters. One way to increase the effective utilization of these inverters is to operate them as reactive power compensators during night to generate reactive power. The line current with high harmonic content generates EMI and causes more heating of the core of distribution / power transformers. A pure sinusoidal line current with low harmonic content is desirable for grid tie inverters. The output current of the inverter is controlled to synchronize it to the utility grid. This paper compares a modified ramp type current controller with hysteresis controller for current controlled voltage source inverter. These control schemes enables the inverter to absorb little active power from the grid and operates as compensator by injecting the reactive power to the grid during night, thus reducing the idle time of the inverter.
